Teacher Comment: Ollie you have done well considering you were absent for two weeks while you competed it and therefore missed out on explicit teaching. I would have liked to see an expanation in your conclusion that discussed why the cokes have different densities and how this effects the health of individuals that drink them etc. Student Comment:
BY OLIVER NORRIS.
TITTLE: To measure the density of Coke, Diet Coke and Coke Zero
INTRODUCTION: I chose this topic because I am interested to see differences between Coke, Coke Zero and Diet Coke. I already know that Diet Coke and Coke Zero contain less sugar than normal Coke.
AIM: By considering all variables my aim is to see which has the most density out of Coke Zero, Diet Coke and Normal Coke.
HYPOTHESIS: As Coke has the most sugars and calories I think that it will sink the fastest because of its high density. The out come of the experiment between Coke Zero and Diet Coke will be questionable as both claim to contain no sugar. I believe that Diet Coke will sink next because it has more Sodium and Additives to make it taste like normal Coke .
EQUIPMENT:
1 empty aquarium tank
60 liters of tap water
1 kg of sugar
1 355ml can of coke
1 355ml can of Diet Coke
1 355ml can of Coke Zero
Scales
Timer
Notebook to record
METHOD: 1.Weigh each can separately and record the weight in your note book. 2. Fill the aquarium tank with enough water to bring it to the top. 3. Add the sugar and ensure it is fully dissolved. 4. Place one can on the surface of the water and start the timer as soon as it is released. Record the time it took to fully submerge. Repeat this experiment with the remaining cans, record information. 5. For the next exercise (you will require an additional person to assist). Place all three cans together on the top of the water and release at exactly the same time. Record details.
RESULTS: By placing each can into the container of water individually and simultaneously it was obvious that the Coke contained the most density.The can of Coke sunk to the bottom of the container within 4.5 seconds.The Diet Coke and Coke Zero remained floating on the surface of the water, well the coke can was fully submerged .
CONCLUSION: After taking into account the variables which were •Weight •Volume •Timing The experiment showed that the hypothesis was wrong between Coke Zero and Diet Coke, i thought that diet coke would sink before coke zero but they both didn’t sink, my hypothesis said that Coke would sink the fastest which was wright.
12/5/11 Aim: our aim was to find what substances A,B,C,D,E,, were.
Hypothesis: Our hypothesis was only right for one of the answers and that was salt, we guessed that salt was B, corn flour was E, cream of tatar was D, icing sugar was C and baking soda was A.
Results: •A Cornflour •B Salt •C Baking soda •D Icing sugar •E Cream of tatar
Method: Put each substance one at a time in the beaker with only a little bit of the substance and a little bit of water aswell water.The substance may fizz up , change colour or do nothing make sure you are accurate with your testing.
Chromotography experiment.
Lesson One - Paper Chromatography
Chromatography is a technique used for seperating mixtures. In all of the variations of Chromatography, a substance is placed onto or into a medium and then a solvent passes through the test substance, some of the test substance may be attracted to the solven and follow it up in the medium. Different types of molecules are transported different distances, causing them to seperate. In these activities, filter paper is the medium, solvent is the solvent and black ink is the test substance. Chromatography is used in crime labs to seperate the components of 'clue' substances such as blood, ink or other mixtures found at the scene of a crime. Chromatograms of these clue substances are then compared with those of the suspected sources.
Chromatography Today's date: Tuesday 10th May 2011
L.I I am learning the process of the chromatography and use this to assist with solving the crime.
Aim: To use chromatography to distinguish which pen was used in the ransom note.
Hypothesis: I think that the blue pen because most teachers write in blue or student
Equipment - Beaker, felt pens, ransom note, filter paper, water, hand lens, masking tape and straws.
Method:
1. Gather samples of pens. 2. Draw a line across a strip of filter paper, 1-4cm from the bottom. 3. Attach to straw with masking tape. 4. Put filter paper in beaker, making sure the ink is at least 1-2cm above the water. 5. Observe. 6. Remove filter when water has travelled about 3/4 of the way up the strip. 7. Compare results with the ransom note results.
ResultsThe green pen was used to write the threatning note we got that answer from the experiment
Conclusion -
The green _ pen wrote the ransom note because the test showed it was the green pen. Explanation2: Monday 7th may
When me and kyle did the dominant side test we both were more dominant on our right side because we both do almost everything on the test on our right hand side the only thing we were left in was the winking and looking through her fingers and thumbs Monday 2 May
Explanation: When the coloured spinning disks colour’s mixed together we mainly saw green the most because it is the darkest colour.We also noticed that blue was the next colour we saw as well.
This table is different from the one outlined in the above Science Fair booklet. There will beno extensions given, Class time will be given for writing up aim, hypothesis, instructions, explanations, diagrams, tables etc and putting displays together. Parents please support your child with carrying out their experiments as this will be the main element of their homework during Science Fair.
